Choosing Your Reverse DCF Assumptions (In Detail)
Even though this calculator solves for growth, your inputs for the discount rate and terminal multiple are critical because they set the parameters for that calculation. They define the required return and future valuation context against which the implied growth is measured.
Selecting the Discount Rate
This still represents your personal required rate of return. Setting a higher discount rate means you demand more return for the risk, which forces the calculated implied growth rate higher to justify the current price. A lower discount rate requires less implied growth.
- Use the same logic as in traditional DCF: consider risk, opportunity cost, market benchmarks.
- Test different rates (e.g., 10%, 12%, 14%) using the slider to see the impact on the implied growth.
Refer to our DCF Analysis Guide for more on choosing discount rates.
Determining the Terminal P/FCF Multiple
This reflects the expected valuation multiple (Price / FCF) at the end of the forecast period. A higher terminal multiple assumes the market will value future cash flows more richly, thus requiring less implied growth today. A lower terminal multiple requires more implied growth.
- Use historical P/FCF charts in the tool as a reference point.
- Consider long-term prospects: a mature, slower company might warrant 12-15x; one maintaining advantages might justify 15-18x+.
- Using a conservative (lower) terminal multiple provides a stricter test. Test different multiples using the slider.
